How it works ?
- In a triangle, suppose we know the lengths of 2 of its sides and a the measure of one angle not included between those sides.
- If this angle is ACUTE, then there 3 possibilities:
- a) No Triangle Exists
- b) Only 1 Triangle Exists
- c) 2 Triangles Exist Interact with this resource for a few minutes.
- Given that red angle A (below) always remains acute, what causes (a) to occur?
- What causes (b) to occur?
- What causes (c) to occur?
